After a series of events in the past three days, I have stopped visiting the kendo club. And after my conversation with Vivian, I understood a few things about Naoto as well as him. He may be annoying but he is also really kind to the people he cares about.
Reminiscing about my actions, I was actually regretting going overboard on her since it appears that it has become a downfall for me. Naoto already didn't talk with me much and after that, I feel like she is completely ignoring my existence.
And since the sports festival was just over, the club was also not very active so I had no way to talk with her. I can't just go to her classroom and start a conversation with her out of the blue. Things have been quite complicated recently.
